MANGLE.

ven t'ed certain new and useful Improvements in Mangles, of which the following is a specification.

This invention relates to improvements on the mangle described in Lewis H. Slaghts United States Patent No. 883497 issued March 31st, 1908, and our object is to improve the construction of the mangle in certain particulars. I

In the original mangle it was found that the evaporated moisture from the goods could not escape quite freely enough during the passage of the goods back toward the front end of the apparatus between the two sets of mangling apparatus. In the improved machine we have therefore so rear-- ranged the aprons as to provide for the greatest freedom 0 escape of evaporated moisture in both the ends and sides of the machine.

Some difliculties were experienced both in the feed to the upper set of mangling apparatus at the feed end of the apparatus and the delivery to the lower set of mangling apparatus at the delivery end thereof, and improved feeding means form part of the present invention.

This present invention also relates to improved means for applying pressure to the rollers which cooperate with the steam chests.

The invention is hereinafter specifically described and illustrated in the accompanying drawings in which- Figure 1 is a side elevation of the improved machine; Fig. 2 an elevation with one side of the frame removed; Fig. 3 a front elevation partly in section showing the means for applying pressure to one end of one of the rollers; Fig. 4 a side View of some of the same parts; and Fig. 5 a plan 'view showing the means for delivering goods between a roller and steam chest at one end of either of the sets of mangling apparatus.

1 is the frame of the machine suitably shaped to support the different parts. On the frame are supported two sets. of steam chests 2 with their cooperating rollers 3. Preferably there will be one roller and steam chest less in the lower set than in the upper, so as to provide suitable space for the aprons carrying the goods as hereinafter described. The rollers may be driven in any suitable manner from the main shaft 4. Trains of gearing for this purpose are indicated in dotted lines in Fig. 1 and need not be specifically described. The rollers have their journals 5 journaled in bearing boxes 6 which are vertically movable in guideways 7 in the'frame. These boxes are each provided with spring tensioning devices adapted to be simultaneously operated to simultaneously tension the rollers alike. These spring tensioning devices each comprise telescopic parts 8 and 9. The lower part 8 is formed on or secured to the box 6, (see Figs. 3 and 4). The lower part 8 is reduced in diameter as shown to provide a shoulder 10 against which bears a coil spring 11, the other end of which bears against the inner side of the end of the part 9. The portion of the part 8 of reduced diameter passes through the end of the part 9 and has nuts 12 screwed thereon limiting the extension of the telescopic parts. On the part 9 are formed one or more pairs of lugs 1314 between which operate one or more eccentrics 15 carried by the shaft 16 suitably journaled on the frame. It is evident that by rotating the shaft 16 that the parts 9 of the tensioning devices may be moved down as may be required to apply any desired tension to the boxes 6, the pressure, of course, being produced by the greater or less degree of tension of the coil springs 11. When the eccentrics are rotated to throw up the parts 8, the springs extend until the upper ends ofthe parts 9 engage the nuts 12, when further movement of the eccentric results in lifting the parts 8 and the bearing boxes 6 to raise the rollers clear of the steam chests and finally sufliciently far to disengage their gears when the clothing is and replaced. The tensioning devices as constructed, it will be seen, cannot possibly be tampered'with after they are in position and the only means for varying their tension is by the rotation of the shaft 16.

readily removed 7 set of rollers. These shafts are operated by A shaft 16 is provided at each end of each means of the following mechanism: A transverse shaft. 17 is provided adjacent the feed end of the machine. This shaft, by means of bevel gearing 18 at each side, actuates the vertical shafts 19. Each shaft 16 is provided, with a worm wheel 20 engaging a worm 21 on one of the shafts 19. The shaft 17 is provided with a wheel 22 by means of which it may be conveniently rotated.

This wheel is preferably grooved to be enof speed as the mangling rollers and the other at a considerably lower rate of speed. This arrangement was not found to be conducive to the most rapid work, and in the present machine we employ a single apron 24. This apron is suitably guided on rollers as usual, but is formed of a plurality of separate ribbonsiinstead of being formed of a continuous belt fabric, (see Fig. 5).. This apron is run at a certain speed, about 25% less than the surface speed of the roller which it feeds. As will be seen on reference to Fig. 1, the train of gears 25 which actuates the apron from the spindle 26 is de signed to give less speed than the train of gears 27 which actuates the mangling roller. The formation of the apron 24 enables us to provide a plurality of fingers 28 which are secured to the roller 29 carrying the end of the apron nearest the mangling roller.

These fingers reach forward into the opening of the space between the first roller and its cooperating steam chest, (see Fig. 2). The goods are thus guided right up to the point at which they are taken hold of by the roller and thus started on their course through the apparatus. The apron traveling at considerably less speed than the roller, the operator can more satisfactorily spread and straighten out the goods, and the goods once taken hold of by the roller are pulled rapidly away from the apron quickly giving the operator the space for placing the next article. The methods for supporting and tensioning the apron are not particularly novel and require no particular description.

An important feature of the invention lies in thearrangement of the aprons for carrying the goods back and forth through the apparatus where they are not subject to the action of the mangling rollers. In the old construction two aprons only were employed. In the present construction four are used, so arranged as to make the spaces paratus.

apron will take the goods as they pass out from between the last roller and steam-chest of the upper series of mangling apparatus -.and carry the goods back to the feed end of the apparatus in contact .with the under sides of the steam chest in the ordinary well known manner. This apron at the feed end of the apparatus brings the goods against the second apron 32 suitably carried on and guided by the rollers 33, which apron carries the goods back to the delivery end of the apparatus. It will be seen that the space between the aprons 30 and 32 is open at the delivery end of the apparatus. Preferably the aprons 30 and 32 are in contact for a short distance at the feed end of the apparatus to properly start the goods back on top of the second apron which is inclined down-' wardly toward the delivery end of the ap- The second apron delivers the goods to the third endless apron 34 which inclines downwardly toward the feed end of the apparatus and delivers the goods between the first roller and steam chest of the lower set of mangling apparatus. This apron is of the ribbon type like the apron 24 and is carried on and guided by the rollers 35. The roller 35 is located as close as possible to the opening between the first steam chest and roller of the second set of mangling apparatus, and is provided with the fingers 36 similar to the fingers 28 employed in connection with the apron 24. It will, be seen that the space between this second apron and the lower set of mangling apparatus is entirely open at the feed end of the machine, giving' free escape for the moisture evaporated. After'traveling through the lower set of mangling apparatus, the goods are taken by the fourth apron 37 and are led back to the delivery end of the apparatus in contact with the under surface of the lower steam chest. This fourth apron is suitably guided on the rollers 38. Suitable tensioning devices 39 of ordinary type are provided in connection with one roller of each of the four aprons so, 32, 34 and 37.
